any proceedings for voluntary liquidation, dissolution or other
 winding up of Lessee, whether or not involving insolvency or
 bankruptcy proceedings, such that the Obligations shall be finally
 paid and performed in full before any payment in respect of a
 subrogation claim by Guarantor shall be made by or on behalf of
 Lessee and (b) notwithstanding the foregoing provisions or any other
 provision of this Guaranty or the Lease, if an Event of Default is
 in existence, Guarantor hereby irrevocably waives and relinquishes
 any and all rights of subrogation, contribution, reimbursement or
 other payment from Lessee or Lessee's estate, whether arising by
 contract or operation of law (including any such right arising under
 the United States Bankruptcy Code) or otherwise arising out of, or
 on account of, any sums which have been claimed or are thereafter
 claimable against Guarantor under this Guaranty, which waiver shall
 be in effect unless and until all of the Obligations shall have been
 finally paid and performed in full. The waiver and relinquishment of
 rights provided for in the immediately preceding sentence shall be
 irrevocable and unconditional regardless of whether any such right
 is reduced to judgment, liquidated, unliquidated, fixed, contingent,
 matured, unmatured, disputed, undisputed, secured, or unsecured.
